Fat people get defensive. I know because I have been one for a damned long time. Luckily, I am over the defensive stage because I'm egotistical enough not to give a fuck what some dude on the internet thinks of me. That said, for many, being fat = poor body image = poor self esteem = over active defense mechanisms. We also tend to circle the wagons around one of our own. Griff lost 100+ pounds, got out of a wheel chair, got his diabetes under control etc. That is a primal success. Now he is happy where he is. Okay, great for him. I would not be happy at 290 and neither would many of the rest of us. So what? Whether Griff never loses another pound or not he still lost a whole person's weight and has valuable advise to give. Just be smart enough to stop listening when it gets to the part that doesn't fit.
It is much like dboxing. He works with athletes. He gets them down to great body fat numbers. Awesome. When I lose another 50 pounds I'll start to listen, but frankly, right now, most of his advice would not fit my situation. Be smart enough to know when to listen.
As for posting pics and credability...how do you define credability? There are some hot looking folks over in the before/after thread but who has more credibility a guy who went from a 400 pound, wheel chair bound, diabetic to a 290 pound far healthier guy or someone who went from 12% body fat to 8%? I can tell you which one will look better in a picture, but speaking as a former 300 pound guy, Mr. low body fat wouldn't have had much to offer me at the beginning. It is about time and place.
When someone is a new poster, 100+ pounds overweight and diabetic then Griff is the perfect source...he lost 100 pounds, he beat his diabetes. If someone is an in shape person who wants to get cut then go read about carb refeeds or whatever. If you weight is stalled out read about IF or Leptin resets. Where we seem to get pissy is that too many of us have one rigid mindset about what works. YMMV is often the rule. Don't take it personally. If someone posts something you disagree with then disagree but don't kill the messanger.
That said, read the F'ing book. It is about as close to 'one size fits all' as I have ever found. Beyond that it's a WOE, it's a lifestyle. Live yours, enjoy it.
